I'm not sure if in Maths teachers imaginations, there's a James bond of maths, out there, and to save the world he has to divide by pi. (in which case they'd pick someone who actually likes maths, anyway) Or, they imagined, either we all collectively or just one of us, has a save the world moment, and it involves solving some maths thing. I don't think they were quite the heroes they imagined themselves. Or maybe they are and this is all out there, and we just don't even hear of it.

The only way you were having a calculator in your pocket was if you hauled a ti-85 around, which no one was ever going to do.
